Title: Method and apparatus for printing photographs
IPC: G03G15/043
Filed: 1975-04-23
Abstract: 1456178 Automatic printer KONISHIROKU PHOTO INDUSTRY CO Ltd 23 April 1975 [27 April 1974] 16761/75 Heading G2A A printer for the production of one or more copies of particular frames of a film-strip (having one or more numbers corresponding to each frame), in accordance with a customer's order sheet, comprises a first memory for storing information representing frames to be copied and number of copies required of each frame and a second memory for storing information representing the position of each frame to be copied relative to a reference position on the film-strip. The reference position may be an aperture indentifying the beginning or first frame of the strip. In the former case, the printer also has means for discriminating between a picture frame representing signal and the strip-beginning signal. Information from a plurality of order sheets (including respective identifying reference numbers) may be recorded manually (on a cassette tape using a key board) whereafter information relating to a particular filmstrip may be transferred to the first memory, using the appropriate reference number, and corresponding reference information recorded in the second memory. Alternatively, information on an order sheet may be fed automatically to the first memory.

Title: Swivel linkage joints
IPC: F16C11/06
Filed: 1932-06-14
Abstract: 393,090. Universal joints. AMAL, Ltd. and BROWN, C., Holford Drive, Perry Barr, Birmingham. June 14, 1932, No. 16798. [Class 65 (ii).] A universal joint, particularly for the rods of motor-vehicle ignition and other control gear, comprises a socket on one member provided with a peripheral slot to receive a stem connecting the other member with a head which swivels in a block rotatably mounted in the socket.; preferably one part of the slot is enlarged so that the head can be inserted when not in the working position, and the parts are retained together, when working, without split-pins or other means. The joint provides larger bearing surfaces, and permits the use of a larger stem under the head, than a corresponding ball-joint. In. the construction shown, a member 2 of case-hardened steel, internally threaded at 12 to receive the end of a rod, is formed with a socket part having a cylindrical bore 3 and a peripheral slot 5 enlarged at one end 6. A brass block 4, fitting into the bore 3, has a bore 9 to receive a case-hardened steel head 7 on a stem 11 of a member which has a threaded part for attachment to another rod. The joint is assembled by placing the block 4 in the bore 3 of the socket and inserting the head 7 through the enlarged part 6 of the slot in the socket and into the hole 9 in the block 4. As the members are turned to their working position the stem 11 passes along the narrow portion of the slot 5, and the head is prevented from disengagement by bearing against the inside of the bore 3 in the socket member ; the ends of the head 7 are made part-spherical to bear properly inside the bore 3 in all positions. The plane of the slot 5 may be offset from, or at an angle to, the axis of the member 2.

Title: Improvements relating to the formation of lubricated metal surfaces
Inventor: HYAMS MONTAGU
IPC: C23C22/46
Filed: 1954-06-08
Abstract: A method of producing a lubricating layer on a metal surface comprises treating the surface with an aqueous acidic composition or orthophosphoric acid or oxalic acid which is chemically reactive with the surface and contains molybdenum disrephide dispersed therein. The composition may also contain (a) a water-soluble salt of phosphoric acid or oxalic acid or both, particularly a heavy metal salt thereof (b) halogen ions (c) accelerators and (d) a thickening agent e.g. methyl cellulose and it may be prepared by dispersing the molybdenum disulphide in the p  acidic solution by means of an acid-resistant dispersing agent, e.g. the sodium salt of a long chain fatty alcohol sulphonate. The composition may be applied to the metal surface by brushing it on and the reaction between the surface and the composition can be accelerated by heat, preferably supplied as direct steam.  The metal surface may be of iron, steel, chromium, metal or ferrous alloys containing chromium and/or nickel and the lubricating layers formed can be used to facilitate plastic deformation, e.g. deep drawing, and on bearing surfaces for sliding and rolling friction.  Compositions given by way of example comprise (a) zinc oxide, phosphoric acid, nitric acid, nitroguanidine, methyl-ethyl cellulose ether and molybdenum disulphide (b) oxalic acid, ferrous oxalate, sodium chloride, sodium chlorate and molybdenum disulphide and (c) oxalic acid, ferrous oxalate, sodium chloride, sodium chlorate, a wetting agent, methyl cellulose and molybdenum disulphide.  Specifications 661,385, 675,024 and 683,954 are referred to.

Abstract: 1,268,895. Delivering sheets. GARTEMANN & HOLLMANN G.m.b.H. 9 April, 1970 [14 April 1969], No. 16958/70. Heading B8R. Flattened paper sacks issuing from a bottom folding machine are fed in overlapped relationship between pressing conveyer belts 1 and between driven and idler intake rollers 5, 6 on to spaced apart conveyer belts 2 running over a slide table 3. The rear edge of each sack swings downwards as it leaves the roller 5 and actuates the feeler arm 7 of a counter 8. When a predetermined number of sacks has been counted, suction devices 15 are raised and connected to a suction source by means of a magnet 17 so as to grip the sheet following a group of sheets to make up a batch. A carriage 13 carrying the suction devices and also carrying pressure rollers 26 moves to the left at the normal speed of the belts 1, 2, while the belts 2 are accelerated so as to create a gap between the gripped sack and the sacks in front. The suction devices are then lowered, the carriage returned, and the process repeated.

Title: Improvements in the production of cyclopentadiene
Filed: 1946-06-05
Abstract: Cyclopentadiene is obtained by heating its dimer by direct contact with an inert liquid heating medium.  This preferably boils or begins to boil at the decomposition temperature of the dimer and is a solvent for hydrocarbons.  Hydrocarbons or mixtures thereof, especially those obtained by cracking or fractionation of petroleum and other oils and having an initial boiling point of 190-250 DEG , especially 220-250 DEG  C.  The dimer may be heated in the liquid medium in a still under a reflux column operated so that the monomer distils.  The dimer is preferably heated rapidly to well above its boiling point, e.g. 220-240 DEG  C., at which temperature at least a substantial part of the liquid medium boils, the rate of feed being the same as that at which monomer is produced and removed.  The liquid medium is periodically purified from the gummy by-products which dissolve therein.  In an example, a hydrocarbon fraction boiling at 0-70 DEG  C., and obtained by cracking gas oil, is stored until the cyclopentadiene is converted to dimer, and distilled up to 75 DEG  C., the residue being fed to a still containing a gas oil fraction of initial boiling point 230 DEG  C., kept boiling, monomer being collected.

Abstract: 1480022 Volume determination: measuring thickness PITNEY-BOWES Inc 25 April 1975 [6 May 1974] 17304/75 Headings G1M and G1X The volume of an article such as an envelope is determined by measuring its thickness at spaced apart locations over an entire surface area of the article and summing the thickness measurements. Envelopes pass in turn between opposed plates 16, 16' carrying pairs of opposed spring-loaded sensing rollers 17, each roller pair 17 providing a thickness measurement. As the trailing edge of an envelope reaches the plates 16, 16', a photoelectric detector causes all the thickness measurements to be added to provide a volume value. In an alternative arrangement, Fig. 2 (not shown), each envelope is indexed in steps past a single vertical row of roller pairs. The weight of an envelope is determined by multiplying the volume value by a density value. Rollers 17 may be replaced by spheres.
